How to convert any of the following formats?

[Pino]

Is there a way to convert AAR or ZIM files to any Android GD compatible format? I was looking for a Czech offline Wikipedia and have found it, but only in AAR and ZIM formats and none of them are supported by the GoldenDict app for Android. I already asked the dev to add the support but he ignores my emails, (even though I have paid for the app...). So the only solution for me seems converting any of the two formats. The question is HOW... Does anyone have any idea, please?

Edit:
Now I've also found a link to the original Wikipedia dump XML file so I'm wondering if anyone knows how to use it with GD on my Android device...?

Pino,
you can use this tools to convert aard to stardict. there is no documentation, so you have to adjust it by youself (you need write new cmd file for your job).
